It's still two point calibration, just the air calib confirmation is removed from user interface...
Calibration window ends two minutes after power on, I suppose the assumption is the head is not yet attached, therefore exposed only to ambient air...
...so be sure not to have the O2 or head only cal kit connected to the head when entering the calibration screen. Been there, done that...
